Clinicopathological Analysis of 907 Major and Minor Salivary Gland Tumors.

PURPOSE: The frequency and types of salivary gland tumors show significant geographical variations. The most common are primary epithelial tumors, with pleomorphic adenoma and mucoepidermoid carcinoma being the most frequent. This study aims to analyze the clinicopathological data of patients with major and minor salivary gland (MiSG) tumors. METHODS: The retrospective study included all patients with major and MiSG tumors diagnosed and treated between January 2000 and January 2019. Files of 907 patients were reviewed and investigated for clinicopathologic features of major and MiSG tumors in Serbia. RESULTS: The majority of tumors were of epithelial origin. Pleomorphic adenoma was the predominant type of tumor, with 35.1% among all tumors on all sites. Adenoid cystic carcinoma and mucoepider-moid carcinoma (with 7.1% and 2.7%, respectively) were the most common malignant ones. The most common localization was the parotid gland. Minor salivary gland tumors comprised 16.43% of all salivary gland tumors in our series, the most common localization being the oral cavity. The results of our study are mostly consistent with the results of other previously published studies. CONCLUSIONS: The most important finding, worth emphasizing, is that the most common malignant major and MiSG tumor in our population is adenoid cystic carcinoma, rather than mucoepidermoid carcinoma, in all investigated localizations. In addition, the nasal cavity is the most common localization among malignant MiSG tumors.

Analysis of reconstructive methods in surgical treatment of nasal skin defects.

Background/Aim: Surgeons often face with the problem when selecting a reconstructive method for nasal skin defects. The aim of this study was to determine functional and aesthetic character-istics of different reconstructive methods used for skin defects in different regions of the nose. Methods: The study involved 44 patients with basocellular carcinoma in nasal area. The nasal skin was divided into four subunits: the tip, the alar lobules, the side-walls and the dorsum. The average skin defect size was 10 mm in diameter. Local flaps and full thickness skin grafts were used in the study. We analyzed the functional and esthetic results of dif-ferent reconstructive methods used for nasal defects in different regions of the nose 12 months after the surgery. Results: The study shows that different reconstructive methods produce dif-ferent functional and esthetic results in the same nasal subunits and that the same reconstructive method produces different re-sults in different nasal subunits. Conclusions: Estimation the postoperative functional and esthetic characteristics of different reconstructive methods is one of the basic preconditions of suc-cessful reconstruction.
